Interior Lamps Dimming
The second group includes lamps which may be dimmed. This group may use a combination of vacuum fluorescent (VF) illumination and incandescent lamps.
• Power window switches
• HVAC control head assembly
• Radio
• The instrument panel cluster (IPC)
When the ignition switch is turned to the ON position, the vacuum fluorescent (VF) display (radio) turns on at maximum brightness. When the park lamps are ON all incandescent back lighting turn ON at the dimming level indicated by the IP dimmer switch. At the same time all vacuum fluorescent (VF) displays dim to match the indicated dimming level. When the headlamp switch is placed in the PARK position, the park lamp supply voltage circuit provides an input to the body control module (BCM). The BCM then supplies voltage to the instrument panel dimmer switch through the instrument panel dimming lamps control circuit. The setting of the instrument panel dimmer switch determines the amount of voltage that the instrument panel dimmer switch supplies to the BCM through the instrument panel dimming lamps low reference circuit. The BCM then sends a pulse width modulated (PWM) voltage to all the interior lamps. All the vacuum florescent (VF) and incandescent back lighting lamps are provided a specific voltage and are then grounded. When the headlight switch is turned to the PARK or HEADLAMP position, all incandescent back lighting turn on at the dimming level indicated by the IP dimmer switch. When the IP dimmer switch is moved from MIN to MAX, all vacuum fluorescent (VF) displays, as well as all incandescent back lighting respond from Minimum intensity to maximum brightness in response to the IP dimmer switch.

I would have it checked for DTC'S - diagnostic trouble codes stored in the BCM !
DTC B2624 Display Dimming Input Range/Performance
The body control module (BCM) supplies voltage to the instrument panel dimmer switch through the instrument panel dimmer switch signal circuit. The dimmer switch varies the voltage and returns the new voltage to the BCM through the dimmer switch signal return circuit. The BCM uses this voltage to determine the illumination level of the instrument panel lamps.

DTC B2625 Display Dimming Pulse Width Modulation (PWM) Output Circuit Range/Performance
The body control module (BCM) receives a variable voltage from the instrument panel (I/P) lamp dimmer switch. The BCM uses this signal in order to vary the illumination level of the I/P lamps. The I/P dimming lamps output from the BCM is a pulse width modulated voltage supply used to light the I/P lamps. If a malfunction occurs in the I/P dimming lamps output circuit, this DTC is set.

DTC B2662 Park Lamp Switch Circuit Malfunction
The park lamps are controlled by the turn/headlamp switch. Positive battery voltage is supplied to the switch through the EXT LP fuse. When the turn/headlamp switch is placed in the park or head position, battery voltage is supplied to the park lamps. The body control module (BCM) is also connected to the park lamp circuit to sense whether or not the park lamps turn ON when the low beam or high beam headlamps are turned ON. The BCM also uses the parklamp battery positive voltage to power the instrument panel (I/P) dimmer output circuit. If the BCM senses that the low beam or high beam headlamps are ON and the park lamp input is not active, DTC B2662 sets.
Do the park lamps work ?

How do i bim and brighten dash light 2002 buick lesabre


bim or DIM ? the dimmer switch ! Interior Lamps
The interior lamps consists of two groups, lamps that can not be dimmed and lamps that can be dimmed. This first group consists of lamps that may not be dimmed. This includes those lamps that may be manually turned on by placing the interior lamp switch to the DOME position, or by opening a door or a compartment:
• Door courtesy lamps
• Footwell courtesy lamps
• Instrument panel (I/P) compartment lamp
• Overhead console courtesy lamps
• Reading courtesy lamps
• Rear compartment courtesy lamp
• Roof rail courtesy lamps
• Sunshade vanity mirror lamps

Interior Lamps Dimming
This group of interior lighting includes lamps which may be dimmed. This group uses a combination of class 2 controlled illumination and incandescent lamps:
• Air temperature switch
• Cigar lighter lamp
• Door switches
• Driver information center (DIC) switch
• Headlamp switch
• Head-up display (HUD) switch
• Heated seat switches
• HVAC control assembly
• Instrument panel cluster (IPC)
• Memory function switch
• Radio
• Steering wheel controls
• Window switches
For the interior lighting to be dimmed the following conditions must be met:
• A low light level has been detected by the dash integration module (DIM)
• Headlamp switch is placed in to the PARK or HEAD position
• Ignition switch is placed in the ON position
Then all class 2 displays and all incandescent back lighting will be illuminated to the level set by the instrument panel (I/P) dimmer switch. When the I/P dimmer switch is moved from MIN to MAX, all class 2 displays and all incandescent back lighting respond from minimum intensity to maximum brightness.
The DIM supplies battery positive voltage to the coil side of the PRK LP relay in the rear fuse block.
When the I/P dimmer switch is moved from MIN to MAX, then the instrument panel module (IPM), W/CJ2, or climate control panel (CCP), W/C67, applies a message to the class 2 communication circuit to the DIM. The DIM then applies a ground to the park lamp relay control circuit. This energizes the PRK LAMP relay and allows battery positive voltage to be applied through the DIMR fuse to the DIM. The DIM then illuminates the following incandescent lamps through the incandescent dimming output circuit:
• Cigar lighter lamp
• DIC Switch
• Headlamp switch
• HUD switch
• HVAC control assembly
• IPC
• Radio
• Steering wheel controls
The DIM also applies a message to the following class 2 controlled illumination components:
• Drivers door module (DDM)
• HVAC control assembly
• IPC
• Radio
The DDM will then send a message through the simple bus interface (SBI) to the RH front door module (RFDM). The door modules will then illuminate the following components through the incandescent dimming output circuit:
• Air temperature switch
• Heated seat switches (W/KA1)
• Memory function switch (W/A45)
• Power door lock switches
• Power window switches
The ground for these components are provided from the DDM and RFDM.
The following components are grounded at G200:
• Headlamp switch
• HVAC control assembly
• IPC
• Radio
• Steering wheel controls
The following components are grounded at G201:
• Cigar lighter lamp
• DIC Switch
• HUD switch

Dim head lamps and day light running lamps won't come on my 2000 Buick lasabre


Daytime Running Lamps
With the daytime running lamps (DRL) programmed to be on, the DRL will operate when the ignition switch is in the ON position, the gear selector lever is out of the PARK position, the headlamp switch is in the OFF or PARK position, and the ambient light sensor indicates daytime conditions. Battery positive voltage (B+) is supplied to the DRL relay coil through the underhood fuse block. Battery positive voltage is supplied through the underhood fuse block FOG/DRL Fuse to the DRL relay normally open contact. The DRL relay normally closed contact receives ground for normal high headlamp operation. When the dash integration module (DIM) determines that conditions are right for the DRL, the DIM grounds the DRL relay coil. This energizes the DRL relay coil and closes the switch to the normally open contact. Battery positive voltage (B+) is supplied to the LH and RH high beam headlamps in series. The high beam headlamps split the voltage and each lights at half intensity. Current will follow the path from the DRL relay to the LH high beam headlamp, HDHIBML Fuse, HDHIBMR Fuse, the RH high beam headlamp, then to ground.
Does your vehicle have
Twilight Sentinel
The twilight delay switch in the headlamp switch is supplied a reference voltage from the instrument panel integration module (IPM). It is supplied a reference ground from the IPM. The switch is a potentiometer that resistance varies as the switch is moved. The IPM receives an input voltage proportional to the resistance of the potentiometer. The IPM sends a class 2 message to the dash integration module (DIM) indicating the on/off status and delay length for the twilight sentinel. With the twilight sentinel in an ON position, the DIM will automatically control the headlamps on/off status depending on the nighttime/daytime status of the ambient light sensor. The DIM will use the twilight sentinel delay length to know how long to keep the headlamps and park lamps on after the ignition switch transitions from ON to OFF during nighttime conditions.

Why wont the headights or running lights work on my 2002 Buick LaSabre?


There are several reasons why your headlamps an running lights don't work , the headlamp switch is a good one ,plus relays an the DIM - dash integrated module an associated wiring ! Here is how the headlamps work , right out of Buick factory service info !
The dash integration module (DIM) provides battery positive voltage to the signal circuits of the headlamp switch. The signal circuits include the headlamp switch headlamps on signal, the flash to pass switch signal and the high beam input. With the headlamp switch in the ON position, a ground path is available for the headlamp switch headlamps on signal circuit of the DIM through the headlamp switch. The DIM provides ground to either the headlamps high beam relay control circuit or the headlamps low beam relay control circuit of the low beam circuit. The position of the headlamp dimmer switch determines which relay control circuit has ground. The DIM supplies battery positive voltage to the relay control circuits, if the headlamps are necessary. The fuse block - underhood supplies battery positive voltage to both relay switch circuits. When the low beam relay control circuit is energized, current flow is to both low beam fuses and to the low beam headlamps. The headlamps have ground at G103 and at G401. When the headlamp high beam relay control circuit is energized, current flow is to both high beam fuses and to the high beam headlamps. The high beam circuit is divided into a left and right side circuit. The current flow of the left high beam is from the fuse to the left high beam lamp. From the lamp, the current flows to the normally-closed contact of the DRL relay to G103. The current flow of the right high beam is from the fuse to the right high beam lamp. From the lamp, the current flow is to ground at G401. When the headlamp dimmer switch lever is pulled toward the driver, the flash-to-pass switch closes. This grounds the DIM flash to pass switch signal circuit. In response to this input, the DIM energizes the HDLP HI BM relay. Both high beams remain on until the driver releases the switch handle. If the low beam headlamps were on during a flash to pass operation, the low beams remain on. The headlights may be switched to high beam with the opposite movement of the headlamp dimmer switch lever.
By running lights , do you mean park lamps or day time running lamps ?
Park, Tail, License and Marker Lamps
The park lamps, including the license lamps, are turned on when the headlamp switch is placed in the PARK or ON position or anytime the headlights are requested. The fuse block - rear supplies battery positive voltage to the switch contacts of the Park LP relay. When the headlamp switch is in PARK or in ON, the park lamp switch on signal circuit of the DIM has a ground path. The DIM provides battery positive voltage to the control circuit of the Park LP relay. When the park lamps and/or the tail lamps are ON, the DIM energizes the park lamp relay control circuit. This closes the switch contacts. Current flows from the Park LP relay to the LH PARK LP and the RH PARK LP fuses. From the fuse, the current flows to the park lamps. The left park lamps are grounded at G103, G401 and G402. The right park lamps and the right tail lamps are grounded at G103 and G401. The DIMR fuse supplies battery positive voltage to the license lamps and to the DIM instrument panel lamp fuse supply voltage - 1 circuit, for interior lamps dimming. The license lamps are grounded at G401.
The best advice I can give is that you take this to a ASE certified professional repair facility unless your a qualified automotive electric repair person !

When switch headlamps from brite to dim they go out also drive light wont come on


First I would suspect the dimmer switch on the steering column or wiring in the column. Second I would suspect a bad ground wire or ground connection. Here is link to a forum where others are having lighting problems with daylight running lights. The whole DRL system is rather a complicated maze of relays and connections, any of which could cause your problem. The tip on the forum to get a wiring diagram form Autozone looks like a good deal.

Why doesn't my speedometer/odometer, horn and headlights work?


Which insturment cluster does your's have ? electronic instrument cluster or standard instrument cluster !

Standard insturment cluster - speedo / odometer
Speedometer/Odometer
The speedometer and odometer provides speed information based on a speed/distance pulse signal from the vehicle speed sensor (VSS). The VSS is mounted on the speedometer driven gear in the transmission.
Could be the VSS is bad .
Horn The horn system includes the following:
  • horn relay
  • horn
  • clock spring
  • steering wheel control switch harness
  • steering wheel pad horn switch, which is part of the driver side air bag module. For additional information, refer to Section 501-20B .
The horn is located behind the front bumper mounted to the radiator support.

Is the air bag light lit on the insturment cluster ? If it is the clock spring could be the problem . If not lit check the circuits from the horn relay .

VEHICLE RELAYS Operation Diagnosis .

Which headlamps don't work ? Low beams , high beams , both ?
  • The high beams are inoperative
  • Bulbs.
  • Circuitry.
  • Multifunction switch.
  • GO to Pinpoint Test C .
  • The low beams are inoperative
  • Bulbs.
  • Circuitry.
  • Headlamp switch.
  • Multifunction switch.
  • LCM.
  • GO to Pinpoint Test D .
Principles of Operation
NOTE: Due to varying wattage ratings and resulting current draw, certain aftermarket headlamp bulbs may cause the lighting control module (LCM) to shut down the short circuit protection, resulting in the low beams becoming inoperative. Verify that the headlamp bulbs meet Ford specifications.
Headlamp System The headlamp system consists of:
  • two aerodynamic halogen headlamp bulbs and retainers
  • headlamp switch
  • multifunction switch
  • lighting control module (LCM)
  • circuit wiring and circuit protection
In normal operation:
  • With the multifunction switch in the low beam position, power is supplied by the LCM to the low beam elements through the multifunction switch.
  • With the multifunction switch in the high beam position (forward detent), power is supplied to the high beam elements and to the high beam indicator in the instrument cluster.
  • When the multifunction switch is pulled toward the steering wheel, the flash-to-pass switch (part of the multifunction switch) is closed and power is supplied to the high beam elements. When the switch is released, they return to low beam operation.
  • The battery saver feature of the LCM will automatically turn off the courtesy lamps, demand lamps, headlamps, or parking lamps under the following conditions:
    • The ignition switch is in the OFF position.
    • The headlamp switch is in parking lamps ON or headlamps ON positions.
    • After 10 minutes.
Headlamp Switch The headlamp switch is a multi-position switch.
  • The positions include OFF, PARK, and HEAD.
  • With the headlamp switch in the PARK position (first detent), a signal is supplied to the LCM which powers the front parking lamps, the tail lamps, the side marker lamps, and the license lamp.
  • With the headlamp switch in the HEAD position, power is supplied to the headlamps through the LCM and the multifunction switch.
  • The panel dim switch (part of the headlamp switch) is located above the headlamp switch. The panel dim switch operates only with the parking lamps or headlamps on.
  • When the panel dim switch is held in the up position, the instrument panel lighting will progressively brighten.
  • When the panel dim switch is held in the down position, the instrument panel lighting will progressively dim.
For additional information, refer to Section 413-00 .
Headlamps On Warning Chime If the headlamp switch is left in either the PARK or HEAD position and the driver door is opened, the LCM will sound a headlamps on reminder chime when the following conditions occur:
  • The ignition switch is OFF with the ignition key out.
  • The driver door is ajar.
For additional information, refer to Section 413-09 .

Inspection and Verification
  1. Verify the customer concern by operating the system.
  1. Visually inspect for obvious signs of mechanical and electrical damage.

Dash lights go on and off while driving, then headlights do the same


Test the electrical circuit's ! Look at a wiring diagram so you know what wire's to test . Watch these video's , buy a DVOM - digital volt ohm meter . Learn to test so you don't listen to guesses .
Basic Electricity for Service Techs Ohm law Current Flow Opens Shorts
Mastering Voltage Drop Testing with Pete Meier and Jerry Truglia
Electric Testing Techniques You Need to Know Free wiring diagrams here . http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine size. Under system click on lighting ,then under subsystem click headlamps . Click the search button then the blue link's . Right away in the first diagram i see the headlamp / panel dimmer switch is a input to the BCM - body control module . I mite think your first response would be to want to replace the BCM ! Reading a discription of how the lights are suppose to work may shed some light on the problem .
Headlamp ON/OFF control is determined by the body control module (BCM) by a signal on the headlamp switch on input circuit when the headlamp switch is in the HEAD position. When the headlamp switch is in the AUTO position, the BCM determines headlamps ON/OFF by the voltage from the ambient light sensor.
If the headlight switch is left in the ON position, the inadvertent power control feature will turn off the headlights approximately 10 minutes after the ignition switch is turned to the OFF position. If the driver places the headlight switch in the ON position after the ignition switch has been turned OFF, or if the ignition switch is in the ACCY position, the headlights will remain on until turned off or the battery runs dead.
The high beam indicator is illuminated when the instrument cluster receives a class 2 serial data message from the BCM that the high beams are illuminated.

Having the vehicle checked for DTC'S - diagnostic trouble codes , BCM - codes ! Need a professional type scan tool . Part stores can't read body codes , dealer or independent repair shop .

DTC B2575
When the body control module (BCM) senses a request for low beam headlamp illumination, the BCM sends a ground signal to the low beam headlamp relay through the headlamp low beam relay control circuit. The headlamp low beam relay will apply voltage to illuminate the headlamps.
DTC B2580
When the body control module (BCM) receives a ground signal from the multifunction high beam or flash to pass (FTP) switch commanding to illuminate the high beam headlamps, the BCM will energize the high beam relay by grounding the high beam relay control circuit.
DTC B2600
DTC B2610
The body control module (BCM) receives a variable voltage signal from the instrument panel (I/P) dimmer switch requesting to illuminate the illumination lamps to a desired intensity. When this occurs, the BCM directly sends a variable voltage based on the I/P dimmer switch position on the instrument panel lamps dimming supply voltage circuit, instrument panel lamps dimming control circuit, and the LED dimming signal circuit.
Voltage for the instrument panel lamps dimming supply voltage circuit, instrument panel lamps dimming control circuit, and the LED dimming signal circuits is from the TBC 2 A fuse in the instrument panel fuse block directly through the BCM to these circuits.

DTC B2620
The BCM directly sends a 5 volt reference voltage to the I/P dimmer switch which is then adjusted based on the I/P dimmer switch position and returned as a dimming return and dimming input to the BCM. The BCM uses this signal to directly control the desired level of instrument panel illumination lamp intensity.

Your best bet , take it to a qualified repair shop .

Don't waste your time looking for a headlamp relay. You will not find one. 1983 Monte Carlo does not use a headlamp relay. Your problem is most likely a defective headlamp dimmer switch. It is located about halfway down the upper left side of the steering column. It is secured by the same screws that mount the ignition switch. It is activated by a metal rod that pushes down on it when you pull back on your turn signal lever. It looks like the picture below.
